Before catapulting, a high-power motor drives a heavy flywheel to rotate at high speed. Once the plane is secured on the catapult shuttle, the flywheel passes kinetic energy to a winding wheel, which then yanks the shuttle through a steel cable to apply force to the aircraft''s landing gear, accelerating the aircraft to take-off speed.
